Beit known that I, JUL'IUs BRENZING'ER,

-a citizen of the United States, residing at Mount Vernon, Westchestercounty, State of y New York, have invented new and use v"linrovements inMachineslfor Lining Covers or Cansvand Jars, specification.

A This invention relates. to a machine forf' ro placing a lining orliquid packing into the e groove of a cover for cans and jars', suchlin- Y Ing subsequentlyserving to form an air-tightK joint between coverandcan.

The machine is so constructed that itwill simultaneously line a largenumber of covers,

'so that acorrespondingl large output is insured. Briely stated, themachineis composed of a rotatable table carrying a number ofglue-delivery nozzles. The covers are sucL 2o cessively -placed upon thetable and held thereto beneath the nozzles by means which also rotatethe covers around their own axes. Thus as the table is rotated thecovers will successively be lined to be finally discharged from achute.

In the accompan g drawings,`Fig1p1re is a front view, part 1n section,of my improved 4machine for ining covers for cans and jars; Fig. 2, alan thereof; Fig. 3, a horiz-om 3o 'tal section on lne 3 3, Fig. 1, withlsome of the arts omitted; Fig. 4, a detail front view of t e coverholding and lining mechanism;

v Fig. 5,' a side view, artly in, section, thereof, showing a cover in pace Fig. 6, a plan ofthe v cover-holding mechanism, and Fig. 7 alongitudinal section through the lining-cylinder.

The letter 'a indicates'the frame of the machine, in which al verticalshaft b is rotatably mounted. 4.Sha't 4I) receives motion from a 4opower-shaft, c by belt c', counter-shaft c2, ear-wheelscSi c, shaft c5,and ear-wheels cG l To shaftb 1s secured a ta le b2, that in y turnlsupports a pot (Z, containin f the glue orv .other lining. T is' liningis .supplied from the pot simultaneously to al suitable number oflcovers A, the drawings showing a machine adapted for the "simultaneoustreatment of six covers. The glue contained in pot d may be agitated bya suitable stirrer (not shown) 5o attached to a spindle d, that receivesmotion by an endless rope d. In order 4to insure a proper dischargeofthe glue through the no'z' ales hereinafter described, the glue iskept unof which the following is a i 'ner hereinafter der a certainpressure by a pressure-pipe d?, .entering ot d and havinv cock d4. Thispipe supplies the pot d with compressed an' or other pressure mediumfrom a 'suitable pressure-tank. (Not shown.) The pot d is provided witha serres of hollow plu s d5, each of which 'communicates by a pipev witha separat-e cylinder e, secured topot d by bracket d. Each cylinder e isprovided with a' discharge-nozzle e', the disl charge-opening ot'4 whichis controlled by a vertically-reciprocating plunger, e2. In order toprevent any clogging of thea nozzle, the plunger e3 isl rovided withalneedle e3, that passes throng the reduced bore oi the` dis.

The plunger e2 is o erated in the following manner: Each cylin er.'e isprovlded w1th an upright c, having-a horizontal arm e5, through anopening of which the upper endv of plunger e2 passes. To'plunger ,e2 1sclamped a crosspiece c", having a pin e7, whlch. 1s guided Withln acorresponding .openlng of arm e5. A spring es intermediate cross-piece cand arm e5 tends to hold plunger e2 in Its lowerniost or closedposition. To cross-piece e.1s plvoted at e9 a two-arm lever f, one endof Whlchcarplunger -is lowered ries a rolllerf,while its other end isprovided l i and i 4 sctsjr2 constitute a fulcrum for lever f, so

that when roller is raised by a cam in manescr'bed the l also be raiseda` ainsi the action o springes to open nozzle e When, on the-otherlhand, roller f is out -of engagement with sald cam, s ring e"v will tiltlever f vdownward to lower p unger e2 and close nozzle e. .l I i Thecam; hereinabove referred .to consists of anumber of curved'cam-sections g', removably mounted upon aiixedrall g, which, is securedtovrame aby brackets c. The rollers j" areadapted to ride upon the cam-'sections g so as to raise lever f and open noz zles e. By removing oneor more o f the cam-,sections the Working lengthof the cam .iscorrespondingly changed to regulatethe timeduringwhich -the -glue issupplied to covers A. The -.cover' "A, which'may be of 4 square, oblong,round, or other shape, is pro-l plunger ev2 `will y IOO frictionally enaged by the roughened edge of afeed-disk fast ona rotatin andvertically-reciprocating s indle h. `he number of disks h correspon s tothe number of nozzles and covers 'to 'be simultaneously lined. Eachspindle h is mounted in a guide or support i, secured to table b2, vandin a bracket c, depending `from such guide. In this way disks h andspindles h will be revolved by table b2 while theyjreceive anindependent rotatory movement in the following manner: The lower end ofeach spindle h is (provided with a pinion h2, engaging a toothe wheel j,loosely mounted upon shaft b. To the hub j of wheel j is secured atoothedwheel jZ, that meshes into a gear-wheel c7, fast on shaft c5.While the inner flange A2 is-enga ed by disk h, the cuter ilange A3 ofgroove A is adapted to be en aged by a'pair of counter-rollers 7c 7c,mounted upon a slide 1c Figs. 5 and 6. The latter is movable within acorresponding way o'f'guide i. Aspring k2 is suspended between a pair oflugs i 7c3 of guide 'i and slide lc', res ectively, and tends to drawrollers lc toward isk h. It will thus be seen that when the grooved-edgeof a cover A is inter osed be tween the rotating disk 7i and rol ers 7cthev groove A will travel around disk h for its entire length at eachrotation of the cover. yThe nozzle e is arranged laterally beyond'thedisk h and midway between rollers 7c above the point marked Xin Fig. 6.The distance between this loint and the disk h should be such that 'ellenozzle is .centered above the groove A. y An up er guard Z prevents thecover from being isplaced vertically while being rotated.

In order to permit lthe insertion of an unlined cover and the removal ofthe lined cover, disks h, as Well as rollers lo, are made displaceablein the' following manner: Each dis is "free to enter a corres endingrecess 'i3 of guide "i 'when spindle h is lowered. To lower the spindle,the hub of pinion h2 is rovided with a collar h3, having pins h4, w ichengage perforations m' of a shippin -lever m. The latter is pivoted'atni2 to a s i er n, fast on and rotating with shaft b. "he free end oflever m is provided with a roller m3, ada 'tcd to engage the lower sideof a curved rai or f arc-sha ed cam o, secured to frame a. A

In this lowered position vpinion h is.countersunk by being received by recess t3, so that the to of disk 7L isiiush withthe face of. guide e. hile disk 7L is lowered its coperatingrollers k are pushed away from the disk in 'the yfollowing manner: Fromeach slide k depends a pin lc, carrying a ro'ller c, adapted to engage acurved rail or arc-shaped cam p, secured to frame a. When the-roler'ksengages rail.I slide' c is pushed toward the ycenter `of t e.machina so that rollers 7c are AmovedA way from -disk h. As will beseen ffroin Fig. '8, cams o and p lare s arranged relativdlyto eachother that they arev enga edahout simiile taneously by rdllersj'n'i3 ands, respectively. In this way the diskh'is lowered while the rollers lcare moved inward, so thatthe coverflanges A2 A3 are simultaneouslyliberated. The lined covers A aredis'charged iii-0in the machine by a'fixed deiiector ,that'conveys them to an iiiclineddeliverym rute g. Inorder to prevent the `plunger 'e2 from opening nozzle e when'a cover isnotinserted lintollhe holding device, there is attachedto slide'lca'narm 7c, which is adapted Vtelen age with its upper horizontal shank k7the uwer end'fo' lever f3, Fig. 5.

The operation is as follows: Talile-'b'2,ito gether with nozzles e andguides 'f, =is sloavlar rotated in the directioirdf arrow B,.'Fig. 2, bythe train of gears above described, and'iis'ks h are simultaneouslyrotated by the engagement of pinions h2 and toothed wheel j.
